Surah Al-Anaam Ayahs #11 Translated in English

And even if We had sent down to you, [O Muḥammad], a written scripture on a page and they touched it with their hands, the disbelievers would say, "This is not but obvious magic."

And they say, "Why was there not sent down to him an angel?" But if We had sent down an angel, the matter would have been decided; then they would not be reprieved.

And if We had made him [i.e., the messenger] an angel, We would have made him [appear as] a man, and We would have covered them with that in which they cover themselves [i.e., confusion and doubt].

And already were messengers ridiculed before you, but those who mocked them were enveloped by that which they used to ridicule.

Say, "Travel through the land; then observe how was the end of the deniers."
